Title: Gravimetric metering device of tapered hopper above vibro feeder for ground glass fibres - comprises vertical stirrer blades diverging downwards from hopper wall to prevent compaction and improve feeding accuracy and rate, for plastics mfr.
Inventor: TOERNER LUDGER
IPC: B65D88/68
Filed: 1991-05-17
Abstract: Device has tapered storage hopper (3), with vertical stirrer blade (5) close to hopper wall, above vibro-feeder (11). The distance of the blade from the wall increases downwards. Pref. baffle (14) with peg (13) projecting inside the stirrer avoids carrying fibres round the hopper by the stirrer. The length of peg (13) is w.r.t. fibre length and metering rate. A partial horizontal baffle (6) opposite the feeder (11) smooths the outflow; and size is determined by the required conveying force. The vibro-feeder (11) and hopper (3) are mounted on separate weigh cells for differential weigh feeding. An adjustable flap (16) projects into the feeder trough (11) to limit the thickness of the glass fibre layer. Rakes (10,17) of shaped bars are oscillated transversely by drive (15) to loosen the fibres and distribute evenly on the feeder. The drives (12,15) for the vibro-feeder and rakes (10,17) are pref. separately controlled for opt. metering accuracy. The stirrer blade(s) (5) pref. extend from mid-height of hopper (3) to near the bottom, and may rotate or oscillate. ADVANTAGE - Avoids fibre compaction at the wall.

IPC: B01D53/94
Filed: 1991-05-28
Abstract: Reducing the start-up retardation of catalyst in an I.C. engine exhaust gas stream (I) is effected by catalytic oxidn. of CO at a point near but before the main catalyst (II) and transporting the resultant heat of combustion into (II) by (I). Oxidn. of CO is carried out in a very short section, pref. shorter than 10mm, cf. the length of (II) and the pressure drip associated with oxidn. is less than 10%, pref. less than 2%. At least 50-60% of the CO but not more than 30-40% of the NOx and hydrocarbons (CnHm) are reacted in this section, in which only Pt is used as catalytic metal. ADVANTAGE - Start-up is improved easily, without reducng the lifetime of (I) or using electric heating. In an example, (II) (1) and ancillary catalyst (III) (2) were placed in a common cylindrical housing (3) with conical inlet and outlet (6,7), fitted in the exhaust pipe (4), with (III) just before (II). (III) had a conical support of metal wire mesh (wire dia. 30mm, free area 55%), pref. of metal suitable for operating temps. above 1000 deg. C, e.g. based on Ni and Cr. It was coated with Al2O3 (pref. 1-5 mg/cm2) and then with 60 micro-g Pt/cm2. (III) touched (II) only at points, so that direct heat transfer from (III) to (II) was only slight. (II) was a commercially available catalyst with a similar support, coated with 1.5 g/l combination of Pt/Rh in 5:1 wt. ratio. It had a dia. of 10cm, length of 15cm, vol. of 1.3dm3 and cross-section of 78.5 cm2, whilst (III) had the same dia. but a vol. of only 0.002-0.003 dm3 and area of 100-150 cm2, making its wt. negligible cf. that of (II). Tests were carried out with 50000 l/l.h exhaust gas with lambda = 1 and a CO content of 1 vol. %. Using (A) (II) alone, (B) the (III)/(II) combination, the temp. which (II) needed to reach, starting from cold (20 deg. C) for 50/90% conversion was (A) 222/242, (B) 186/214 deg. C for CO, (A) 262/392, (B) 222/308 for CnHm and (A) 214/226, (B) 174/204 deg. C for NOx. In an engine test run, the overall conversion was (A) 74, (B) 81% CO, (A) 82, (B) 90% CnHm and (A) 62, (B) 70% NOx.
